I tuned the 13 Ram 5.7 qc 2wd with the canned bully dog tune a few days ago, put maybe 100 miles on it so far. Installed the performance tune, truck has 92 octane gas in it for past 2 fill ups. In the tune I just turned off mds, didn't mess with anything else. Truck has more midrange - top end power, but around 30-35 mph cruising, seems to lug, like it is between gears and have to push gas more to get it to stop, kinda reminds me of when mds would activate. Is that due to truck is relearning shifts? Truck Is all up to date with maint and only 40k miles, only mods are catch can and k&n drop in filter. Last month tranny fluid was changed, gear oil, new mopar plugs and PVC, also throttle body cleaned and broken header bolt fixed .
